Shifting into reverse
Stop the vehicle completely.
Pull gearshift lever up and shift in 
Rreverse.
!Downshifting gears leading to overrev-
ving the engine can result in engine 
damage that is not covered by the 
Mercedes-Benz Limited Warranty.
Do not exceed the engine speed limits 
(page 324).
Never hold the vehicle stopped on a hill 
by using the clutch pedal. The clutch 
may be damaged which is not covered

195 Controls in detail
Driving systems
1Set current or higher speed
2Set current or lower speed
3Cancel cruise control
4Resume at last set speed
Setting current speed
Accelerate or decelerate to the desired 
speed.
Briefly lift1 or depress2 the cruise 
control lever.
The current speed is set.
Remove your foot from the accelerator 
pedal.
Cruise control is activated.Canceling cruise control
There are several ways to cancel cruise 
control:
Step on the brake pedal.
or
Briefly push the cruise control lever to 
position3.
Cruise control will be canceled. The 
last speed set will be stored for later 
use.iOn uphill or downhill grades, cruise 
control may not be able to maintain the 
set speed. Once the grade eases, the 
set speed will be resumed.
!Moving gear selector lever to 
positionN while driving also cancels 
cruise control. However, the gear se-
lector lever should not be moved to 
positionN while driving except to coast 
when the vehicle is in danger of skid-
ding (e.g. on icy roads).iVehicles with manual transmission: 
The set cruise controlled speed is 
switched off when declutching exceeds 
four seconds during downshifting a 
gear.iThe last stored speed is canceled when 
you turn off the engine.

228 OperationDriving instructionsTire speed rating
Regardless of the tire speed rating, local 
speed limits should be obeyed. Use pru-
dent driving speeds appropriate to prevail-
ing conditions.C 230 Kompressor (standard in U.S.A.; 
optional in Canada), C 320
Your vehicle is factory equipped with 
“W”-rated tires, which have a speed rating 
of 168 mph (270 km / h).
An electronic speed limiter prevents your 
vehicle from exceeding a speed of 
130 mph (210 km / h).
C 230 Kompressor (standard in canada; 
Canada only)
Your vehicle is factory equipped with 
“H”-rated tires, which have a speed rating 
of 130 mph (210 km / h).
An electronic speed limiter prevents your 
vehicle from exceeding a speed of 
130 mph (210 km / h).
Winter driving instructions
The most important rule for slippery or icy 
roads is to drive sensibly and to avoid 
abrupt acceleration, braking and steering 
maneuvers. Do not use the cruise control 
system under such conditions.
When the vehicle is in danger of skidding, 
move gear selector lever to positionN or, 
in case of manual transmission declutch. 
Try to keep the vehicle under control by 
corrective steering action.
Warning!
G
Even when permitted by law, never operate 
a vehicle at greater than the maximum 
speed rating of the tires.
Exceeding the maximum speed for which 
tires are rated can lead to sudden tire fail-
ure, causing loss of vehicle control and pos-
sibly resulting in an accident and/or 
personal injury and possible death, for you 
and for others.
iFor information on tire speed rating for 
winter tires, see “Winter driving” 
(page 247).
iFor information on driving with snow 
chains, see “Snow chains” 
(page 248).
Warning!
G
On slippery road surfaces, never downshift 
in order to obtain braking action. This could 
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.

The Research Octane Number for gaso-
line as determined by a standardized 
method. It is an indication of a gaso-
line's ability to resist undesired detona-
tion (knocking). The average of both 
the ->MON (Motor Octane Number) 
and RON (Research Octane Number) is 
posted at the pump, also known as AN-
TI-KNOCK INDEX.
Shift lock
When the vehicle is parked, this lock 
prevents the gear selector lever from 
being moved out of positionP without 
SmartKey turned and brake pedal de-
pressed.
